U.S. film director Oliver Stone gestures during a news conference after arriving at Villavicencio airport December 29, 2007. The Venezuelan mission to pick up three hostages held for years by Colombian rebels in jungle camps was delayed again on Saturday because guerrilla leaders have not given the final go-ahead. Former Argentine President Nestor Kirchner and officials from France and Switzerland were among the envoys who flew to Colombia in executive jets. Stone, who is working on a movie about Latin America, joined them. REUTERS/Jose Miguel Gomez (COLOMBIA)
